Cylinder Deactivation Hydraulic Circuit Bank 2 Low
What it means
The engine control module has detected low oil pressure in the bank 2 hydraulic circuit responsible for cylinder deactivation. Below the calibrated threshold the switching lifters cannot collapse and cylinder deactivation on bank 2 is disabled until pressure recovers.
